It's only about $30 more than the I-Pac. It will save me a bunch of trouble and it will make wiring everything as easy as pie. :( I was trying so hard to keep this project as cheap as posible... Every day the cost goes up more and more and I'm not even adding more features. --- End quote --- Do what you want but if you take your time a mouse hack is no problem. Used micro$oft ps2 mice are dirt cheap. If your looking to save some dough a mouse hack is your best bet. |

Does anyone now where I can find info that explains the meaning of active high/active low? What about unbuffered/buffered (of course I mean in relationship to a Track Ball)? --- End quote --- I found a PowerPoint lecture that might help you here. Basically Active High or Active Low refers to which part of the digital signal the circuit is "keying off of", the high or low side. The active low optics in my trackball didn't have anything to "pull" the voltage all the way up to the "high" threshold so the mouse board could recognise it. That's the reason for the "pull-up" resistors. Hopefully that didn't confuse you too much. |

It seems as thought the "mini-pac" version of ultimarcs trackballs is modified by adding the pull up resistors needed to use a mouse hack or mini-pac which does not have the resistors on board. Mouse hack here I come... |
